Description: An Earthship is a passive solar house that is designed to be off the electrical grid. It is generally constructed with natural and recycled materials. Much of the structure of the house is made with recycled tires that are filled with dirt. Thermal mass from the dirt, solar energy from the Sun, and cross-ventilation are used to keep the temperature within the house in a comfortable zone. This phenomenon can be used study thermal energy transfer, energy conservation, and human sustainability.
